The most reliable way to stop French doors blowing around is a solid stop that catches the door before it opens fully. Closers and chains help much less than people hope.
Hold the door early, before the wind builds speed behind it, and fit the stop where nobody will trip over it.

What people who fix this say
The best detail comes from a Fine Homebuilding forum thread. It dates from 2005, so the product links are old, but the lessons hold.
One builder made a freestanding stop from a 4 inch square tube welded to a flange, about 3 feet tall, with a rubber stop that catches the door near handle height at about 110 degrees. He called it the only thing that had worked at all, though a door on his building still blew off every 12 to 18 months.
Another poster uses floor stops set within a foot of the wall, where people do not walk. He says they hold doors just fine.
Where to put the stop
The stop has to slow the door well before it opens fully. A door that reaches the stop at speed builds momentum, and banging against a stop can damage the door.
Near the wall is the best spot for a floor stop. On a deck, a stop in the walking path becomes a tripping hazard.

Fix whatever you choose into solid framing, not loose trim, because wind loads are bigger than they look.
Magnetic catches
First4Magnets sells a magnetic stop for patio, bi-fold and French doors. It sticks the door to a wall, or to the parallel folding door, and releases when you pull. The curved design connects even at a slight angle.
It is the maker’s page, and it gives no pull force or door weight rating. Ask for the rating before you trust it on a heavy door in strong wind.

Closers and chains
Opinions split on closers. One poster calls them pretty useless against a strong wind because they stop the door suddenly instead of slowing it. Another says they at least keep the door from bashing a stop and bouncing back.
Surface-mounted closers suit steel or fiberglass doors. Concealed ones need mortising into the door and may not suit a wood-clad door.
Chains are the weak spot. One poster reports that wind straightened chains into wire and tore out the anchors.
What I would fit · James Davis
I would start with a solid stop within a foot of the wall that catches the door well before full swing. I would skip chains and treat a closer as an extra, not the main fix.
Before you fit anything
- Find the point where the door should stop, well short of full swing.
- Check the framing behind where the stop will go.
- Keep the stop out of the walking path, especially on a deck.
- Ask for a pull rating on any magnetic catch.
- Check that the door can take a bump, including the glass edges.
